Earlier this week, Environmental Defense and DuPont released a draft strategy that will enable firms that manufacture or use nanomaterials to evaluate and manage environmental risks. The six-step strategy is the product of a partnership that began in September 2005 to encourage the responsible development of nanotechnology-based products. The Nano Risk Framework establishes processes for companies to use to evaluate potential risks, determine staff roles, and gather information. Furthermore, it recommends the use of life cycle analysis to address material sourcing, workers’ exposure, and disposal. For those who are interested in contributing to the development of this framework, Environmental Defense and DuPont will be accepting comments from the public until March 30 at firstname.lastname@example.org.
